Yes, you could run the app like:
WINEDEBUG=+relay,+seh,+tid wine app_name.exe &>/tmp/log
The debugoutput (in /tmp/log) will be huge, if you put it (bzipped2) up somewhere i could have a look if there's an obvious reason for the crash. Btw: i guess the app has no free download, so we could check ourselves?
